Strange striped bars in Waterfall View


Can someone explain what it means when the bars are striped like in this test run

They are not solid color for connect and download content part, they are mixed. It feels that something is wrong here.


Each of the dark stripes are when data is coming in from that request. Since there are a bunch in parallel they are competing for bandwidth and the data is basically interleaved across multiple requests.

It looks like the server isn’t sending the HTTP/2 responses correctly since Chrome requests them with the “exclusive” bit and in an explicit order.


Thanks for the replay. How can you see that “Chrome request them with the exclusive bit and in an explict order”? Is there somewhere on webpagetest I can see that?
